Original application filed October 10, 1927, Serial No. 225,320. Divided and this application filed.

February 15, 1929.

This invention relates to an improved braiding machine adapted particularly for producing the improved braid set forth In my copending application Serial N 0. 225,320,

' the width of the flat braiding extending diametrically of the tubular braiding andinterwoven with the latter at spaced-apart intersections of the two braidings; as fully described in connection with the accompanying drawings.

Fig. 1 is a side view, and Fig. 2 a cross sectional view, indicating a particular integrally formed braid which my improved machine is adapted to produce; and F1g 3 is a diagrammatic view showing the novel arrangement of carrier'courses provided in a braiding machine of otherwise ordinary construction, to enable the production of such novel braid.

A composite braid, similar in a general way to that indicated in Figs. 1 and .2, has

. heretofore been produced by securing to opposite sides of an ordinary flat braid, as by means of sewing, separately made cord braidings which provide the cord effect particularly desired on opposite sides of the edge portion of. the fiat braid shown. Effort has also been made to produce such cord effect in an integral construction, by interweaving with the flat braid-transverse looping threads arranged to fold around and.

secure to the sides of the flat braid, suitable longitudinal filler threads, so as to prov1de a reenforcing longitudinal rib on each side of the braid; such integral construction being readily produced upon a known type of braiding machine having a transverse carrier course adapted to carry such looping threads across the path of the usual flatbraiding carriers. I have found however that a cord efi'ect having the functional characteristics of the composite braid referred to and which are practically required in such braid, cannot be provided by such an integral formation of the side reenforcing as is above referred to; and my invention therefore consists in providing for the production of an actual braided-cord eifect' integral with the main flat braid, and for Serial No. 340,161.

satisfactorily producing such an integral structure continuously and rapidly.

To this end I provide for simultaneously producing a fiat braid 10, extending the full width of the fabric, and a tubular braid having a portion 10* of the flat braid extending diametrally through it so as to be intersected by the crossing wall of the tubular braid at two points 13 and 14 respec tively, spaced-apart to correspond with the diameter of the tubular braid; the interbraided threads which form the tubular braid, crossing the flat braid and being interwoven therewith at each of said spacedapart intersections 1.3 and 14:; and the side portions of the tubular braid which overlie the respective sides of the diametral flatbraid portion forming in connection with said flat-braid portion 10, twin tubular reenforcements 11 11 on opposite sides of the flat braid. To give desired cord effect to these tubularly braided reenforcements on each side of the flat braid, any desired numher or size of longitudinal'fillers are pro- Thecourse for the flat braiding carriers 7 f is indicated by the full lines a, while the paths of the oppositely moving tubular braiding carriers t and t are indicated by light dotted lines and heavier dotted lines 6 and 0 respectively; these paths 6 and ointersecting as usual on the side braiding circles 2021 and 22-23, but providing ordinary crossovers for the carriers t, t between the racecircles 2425, and 26-27, so that all the carriers on paths 1; and 0 pass the like crossover for carriers f f of the flat-braiding course a, as guided by the usual star plates 8 s at the points of intersection, and so interweave with the flat braid forming the top edge of the latter as indicated at 13, and also at a point 14 spaced-apart two racecircles therefrom. Thus the tubular braiding'efi'ected on the courses 6 and 0 provides twin filler spaces. on the sides 01' the diametrical dividing portion 10 of the flat braid formed; between which ortion and the braided-side walls of the tu ular braiding, desired longitudinal fillers 15 may 'be introduced -'so as to form substantial cord reenforcements of desired body and firmness.

What I claim is: A braiding machine comprising a tubularbraiding carrier course having;- separate serles of carriers continuously" traversed thereon in opposite directions, and an intersecting fiat-braiding carrier course having carriers returningly traversed thereon; the respective carriers bein simultaheously operated and said'courses being provided with carrier cross-overs at their separated points of intersection.
